7 Claims.

This invention relates to' new and useful improvements in a safety cap for a knitting needlepoint.

The invention has for an object the use in combination with a knitting needle of a flange mounted on the knitting needle spaced slightly of frictionally maintaining its position on the needle.

Still further the invention proposes a novel arrangement for increasing the frictional resistance between the member and the needle.-

For further comprehension of the invention, and of the objects and advantages thereof, refer- 0 ence will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a ma- 25 terial part of this disclosure:

/ I Fig. 1 is a side elevational view of a knitting needle with a safety cap constructed in accordance with this invention and associated therewith.

Fig. 2 is -a fragmentary enlarged detailed view 0 of a portion of Fig. 1 showing the member on the pointed end of the needle and showing certain parts in section.

Fig. 3 is a fragmentary enlarged sectional view illustrating a portion of Fig. 2.

Fig- 4 is a transverse vertical sectional view taken on the line 4-1 of Fig. 3.

.Fig. 5 is another sectional view similar to a portion of Fig. 2 but illustrated on an enlarged scale and disclosing another embodiment of this 40 invention.

Fig. 6 is a sectional view taken on the line 68 of F18. 5.

The safety clip for knitting needles, according to this invention, is used in combination with a 45 knitting needle II. This knitting needle has a pointed end l0 and a blunt end I 0 A flange I I is permanently mounted on the knitting needle and spaced inwards slightly from its blunt end. This flange may be fused or secured to the mate- 50 rial of the needle in any convenient manner. A member I! is normally mounted on the blunt end of the needle, as illustrated in Fig. l, and is removable and engageable on the pointed end l0 of the needle as illustrated in Fig. 2 for prevent- 55' ing knitting loops from dropping off the needle.

This member l2 comprises an annular rubber member. Frictional resistance is depended upon to maintain the member l2 in its various positions on the knitting needle.

The annular member I2 is provided with a rigid 5 ring I3 of composition material or other rigid material. embedded within a peripheral groove l4 formed in the annular member l2 for holding the outer area of the member from expanding. Consequently, when the member I2, which is made 10 of rubber, is forced upon the knitting needle the portions between the knitting needle and the ring 13 will be compressed. This compression is depended upon to frictionally maintain the position of the member on the knitting needle.

In Figs. 5 and 6 another embodiment of the invention is disclosed which is somewhat similar to the form shown in Figs. 3 and 4, distinguishing merely in the fact that the rubber member i2 is provided with a pair of interengaged rigid annular or ring elements l3 and I3" arranged in a manner so that the material of the rubber member l2 adjacent the knitting needle Ill may be more securely clamped. Specifically, the annular member I3 is the outer one of the two and is formed with a slot l5 through which a pin l6 extends. This pin is permanently mounted on the inner annular member J3. The adjacent faces of the inner and outer annular members l3 and I3" are elliptical, as illustrated in Fig. 8, the major axis being on the vertical, and the minor axis being on the horizontal. The inner annular member I3" is formed with a split l8 in the vertical direction, directly opposite the pin I6.

with the parts as illustrated in Figs. 5 and 6 the member l2 may be slipped upon the knitting needle. If it is desired to securely mount this member on the needle the pin I6 is moved to the other end of the slot l5. This rotates the inner annular member l3" relative to the outer memher [3. Thus the major axes of the elliptical surfaces of these annular members are moved out of alignment with each other, and the side portions of the annular member l3" will be forced together, compressing the material of' the rubber member I! and so adding to the frictional re-' sistance of the member I! on the needle Hi.

It is to be understood that the member I2 may be of rubber or of any suitable material such as felt, cork, etc.

- right is reserved to all changes and modifications fined in the appended claims.

. Having thus described our invention, what we claim as new, and desire to secure by United States Letters Patent is:

' 1. In combination with a knitting needle, a flange mounted on said knitting needle spaced slightly from itsblunt end, and a member mounted on said blunt end and removable and engage-' able on the pointed end for preventing loops irom dropping oil the needle when not used, said member comprising an annular ring of rubber, an annular ring of rigid material embedded therein.

2. In combination with a knitting needle, a flange mounted on said knitting needle spaced slightly from its blunt end, and a member mounted on said blunt end and removable and engageable on the pointed end for preventing loops from dropping an the needle when not used, said member comprising an annular ring of rubber, an annular ring of rigid material embedded therein, specifically within a groove in the Outer sides thereof.

3. In combination with a knitting needle, a flange mounted on saidknitting needle spaced slightly from its blunt end, and a member mounted on said blunt end and removable and engageable on the pointed end for preventing loops from dropping ofi the needle when not used, said member comprising an annular member of rubber having a groove formed in its periphery, a pair of interengaged rings of. rigid material mounted in said groove, the inner ring being split,

' the contacting faces of said ring being slightly elliptical, and means for turning said rings slightly relative to each other.

4. In combination with a knitting needle, a flange mounted on said knitting needle spaced slightly from its blunt end, and a member mounted on said blunt end and removable and engageable on the pointed end for preventing loops from dropping oi the needle when not used, said member comprising an annular member of rubber having a groove formed in its periphery, a'pair of interengaged rings of rigid material mounted in said groove, the inner ring being split, the

contacting faces of said ring being slightly e1 liptical, and means for turning said rings slightly relative to each other, comprising a pin projecting from .the inner ring andengaging through a slot formed in the outer ring.

5. In combination with a knitting needle, a member engageable upon the pointed end 01 said needle for preventing loops from dropping 01! said needle when not in use, comprising an annuiar rubber member slidably engageable on said needle and formed with a groove in its periphery,

a. pair of interengaged metalrings mounted in said groove and having their engaging iaces elliptical, and means wherebysaid inner ring may be moved relative to said outer ring tocompress said rubber member to increase the frictional engagement of said member onsaidknitting needle. t V

6. In combination with a. knitting needle, a member engageable upon the pointed end of said needle for preventing loops from dropping off said needle when not in use, comprising an annular rubber member slidably engageable on said needle and formed with a groove in its periphery,

a pair of interengaged metal rings mounted in said groove and having their engaging faces elliptical, and means whereby said inner ring may be moved relative to said outer ring to compress said rubber member to increase the frictional engagement of said member on said knitting needle, comprising a pin mounted on the outer periphery of said inner ring and projected through a slot formed in said outer ring to be manually gripped for turning the inner ring.

7. In combination with a knitting needle, a member engageable upon the pointed end of said needle for preventing loops from dropping onsaid needle when not in use, comprising an annular rubber member slidably engageable on said needle and formed with a groove in its periphery, a pair of interengaged metal rings mounted in said groove and having their engaging elliptical, and means whereby said inner :1- may be moved relative to said outer ring to compress said rubber member ,to increase the iris tional engagement of said member on said knit ting needle, said inner ring being formed with a radially extended split, so that the operative diameter'ofsaid inner ring is decreased as said inner ring is turned relative tosaid outer ring to compress said rubber member.
